PAPER CAP roa MILK-BOTTLES Specification of Letters Patent.

Application filed June 14, 1913. Serial No. 773,644.

To all whom it may concern Be it known that I, GEORGE H. DAVIS, citizen of the United States, residing at Port= land, inthe county of Cumberland and State of Maine, have invented certain new and useful Improvements in Paper Caps for Milk-Bottles, of which the following is a specification, reference being bad therein to the accompanying drawing. v

This invention relates to closures for receptacles, and more particularly to improveinents in paper caps designed for such use as in connection with milk bottles.

a The object of the invention is to furnish a paper cap of the type referred to, adapted not only to perform thefunctions of an ordinary disk fitted into a seat formed in the mouth of the bottle, so generally in use, but to also prevent accumulation of extraneous matter in t e mouth of the bottle above said disk, whic frequently works through the disk around the edge of the same, or when punctured or raised fromits seat, under the expansion of the contents 'in cold weather,

or otherwise, resulting in the contamination of the milk; and further, to protect the top surface of the wall of the bottle surrounding the mouth, and the circumferential bead at the side thereof so that when the cap is removed the contents may be poured outwardly over a clean surface of the bottle devoid of the accumulation of dust, germs, etc.

My improvements are capable of embodiment in many forms and devices capableof producing the satisfactory results above suggested, but for the purpose of the present application, it will be'necessary to illustrate but a few of the preferred forms. The characteristics of these will be apparent from the detailed description hereinafter contained, when read in connection with the accompanying drawing, forming a part hereof, and wherein said preferred embodiments are illustrated.

In the drawings :Figure 1 is a vertical sectional View, partly in perspective, of a standard type of milk bottle having my improved cap applied thereto; Figs. 2 and 3 are perspective views of. the two separable members of the cap removed from the bottle; Fig.4 is a view similar to ;F ig. 1, of a second embodiment of the invention; Fig. 5 is a like view of a third embodiment, and Fig. 6 similarly represents a fourth embodiment of the invention.

Referring more specifically to the drawings, and first with reference to Figs. 1, 2 and 3 of the same, A represents the usual neck of a glass bottle, having an annular shoulder B on the interior thereof at the mouth of the bottle constituting a seat for the usual disk closure, for the improvement of which the present construction has been conceived. As distinguished from the usual flat disk, I provide what-may be properly termed a'cup-cap, the bottom G of which is adapted to firmly seat upon the annular shoulder B to constitute theimmediate closure for the mouth of the bottle to protect the contents on the interior of the bottle, and the upwardly projecting annular flange D of which forcibly engages the inner wall E of the bottle above the shoulder to create a seal therearound. The width of the bottom C and the diameter of the annular flange D are such that the cup-cap when forced home will have the sealing engagement with the shoulder and wall, as stated, it being understood that the material of which the cup-cap is formed is preferably a Patented Aug. 18, 1914.

card-board to give sufiiciont rigidity for the described, and which latter is similarly formed of card-board, is paraflined or otherwise treated to render the same impervious and to assist in causing the binding and sealing engagements.

E is the top of the upper member of the cap, the same in this instance being substantially flat and of a size to extend over the entire upper surface of the bottle mouth, the marginal part of the top being bent downwardly to provide a depending flange F surrounding the beaded portion G of the bottle, and thence upwardly and inwardly over the upper surface of the bottle mouth and below the top E, as represented at G, so as to terminate in an annular depending flange H adapted to be received within the cup-cap CD, the annular flange H referred to being of a size to cause a firm frictional engagement between the outside of the same and the inner surface of the flange D to maintain the two members of the cap together when in use, but permitting separation thereof. When the parts, just described, are associated, as shown in Fig. 1, a space I is left therebetween, A cap thus constructed will protect all of the parts immediately surrounding the mouth of the bot- .may be withdrawn by 'puncturin tle upon the disk, and so liable to fall into f the bottle contents when the disk is removed. In the present instance, the outer member the top E over the space I, all d1rt,etc., eing discarded with said member, and then upon removal of the member C, everything associated therewith will be clean and sanitary, and the member C may be subsequently employed to cover the bottle when the contents of the same have been but partially removed.

In addition to the foregoing, should for any reason the outer member E be broken, matter could not drip or fall therethrough into the bottle contents because of the collecting character of the cup-cap which would simply retain such matter until both members of the cap were withdrawn.

Within the space I a germicide or a milk preservative might be introduced in such instances as might be found desirable.

Referring now to Fig. 4, the cup-cap is represented at J and is marginally continned over and around the beaded upper edge K'of the bottle mouth, as shown at L,

intothe hollow portion of the member J will create a firm bindin engagement between the contacting sur aces of the same. In this instance, as well as in the former instance, the parts of the cap may be assembled before inserting them in a bottle, or

they may be inserted individually, the marginally depending flanges in each instance having suflicient flexibility to be forced over i the beaded edges of the bottle mouth.

A space N is provided between the two members J and M similar to the space I be- 7 tween the members 0 and E above defined.

In Fig. 5 the cup-cap O is quite similar to the cup-cap J in Fig. 4, save that the marginally depending flange P instead of fitting around the beaded portion Q, of the bottle interlocks with a hook-like rim R on the I depending marginal portion of the flat top the wall V of the member S into firm bindv mg engagement with the adjacent wall of the bottle mouth. This structure is particularly efiicacious in connection with bottles wherein the \wall V inclines inwardly as shown in Fig. 6, or is of a notched construc tion to provide an overhanging wall to 'assist" in maintaining the usual disk in place.

The construction of Figs. 5 and 6, like the first two forms described, are of paraflined paper board bent to the desired shapes.

space in the cup and having a depending portion fitting within the cup and leaving the central portion of the bridging member free relative to the cup member.

2. A device of the character described comprising a paper cap for milk bottles consisting of two members, one of cup shape adapted to fit within the mouth ofa bottle, and, the other adapted to bridge the. open space in the cup and having a depending portion fitting within the cup acting to force the walls of the cup into sealing-engagement with the bottle.

3. An article of the character described com prisin a paper cap for milk bottles consisting of two members secured together, one of said members being ofcup formation to provide an interior space between the two members, and said cup being adapted to be forced into sealing'engagement with a bottle mouth, and the two members having interfitting edge portions.

4. An article of the character described comprising a paper cap for milkbottles consisting of two members secured together, one of said members being of cup formation to provide an interior space between the 'two members, and said cup being adapted to be forced into sealing engagement with a bottle mouth, and the two members having .interfitting edge-portions separably engaging each other.

In testimony whereofI aifix my slgnature .in. presence of two witnesses.
